Guard 1: "So do you think we should ask him abou..."Huh, that's actually a pretty good comparison. Except instead of it just being a strong-willed father against a strong-willed daughter, it's dictatorial dad against a bullying daughter, and also their relationship has weird, obsessive undertones coming from both parties that no one knows how to deal with because either A) they have no idea how to bring it up (Milli and Oswald) or B) they don't want to get shot (everyone else).
Guard 2: "Shut up! Before you get us both killed."
I can just see this one presidential guard from the Custer and Steel era constantly keeping his mouth shut and staying alive in the face of how deranged his bosses are. Somehow managing to outlive both his bosses before his grandson ends up protecting Oswald and stck in the same scenario.
